- Application filed-November 2a, 1894, sermmszasvz. (No model.)

To all whom it may concermn Be it known that I,

and, in-thecounty of 'Cuyahoga aiidState of Ohio, haveinvented certainnewand useful Improvements in-Wrought-Meteil J bist-Hang ers; and I dohereby declare the following to be a full, clear, andfexact descriptionof the -inventi.on,such the art to which itfappertains toimake and aswill enable others skilled in use thesame. I

My invention relates towrought metal joist hangers; and the object oftheinvention is to produce a wroughtmetaljoist hanger which shall bestrong enough for the intendeduse, and,'in my opinion, stronger than'anymetal joisthanger heretofore made of equal weight, and which shall alsobe cheaper than any wrought metal-joist hanger heretoforem'ade. Theinventionconsists of the described hanger, the blank from whichit ismade, and

themethod of forming saidblanks with no.

considerable waste of material.

In the drawings, Figures 1 and 2 are per:

.spective views of two forms of bars from which the hanger blanks inaybe cut alternately from opposite sides. Figs. 3 and dare end views ofthe. bars-shown in. Figs. 1 and 2 rethrough which spectively; and Fig. 5is a of the com'pleted'hanger.

Referring to the parts by letter, A Arepresent the two substantiallyparallel vertical sides of the hanger;B,the intermedia.tehorizontalshelf and O 0 represent flanges which perspective view are integral'withthe rear" edges of theme I sides and lie at right angles thereto.Theseflanges extend beyond the ends of the sides and are bent backwardinto] planes substan- "tially atright angles to the sides themselvesand-parallel to the. shelf B, thereby forming arms C C which are adaptedto. lie on top of and to be secured to the beam by whichthe hanger is tobe supported." "Holes c are'formed in the flanges CO and in the arms0"(3,

I means of which the hanger may be secured to said. beam.

. the rear edge of the shelf. 5;

part of the-blank whichforms the shelf is cut isshown-in the drawings,there is In forming the hanger the realpart of that JAMEsHV N Donn, aStates, residing aiFGleve pass the screws or spikes by In the preferredform, which no flange onbifiwhereby the bending of the flanges on thesides into the desired position may be effected without danger that theblank will be split vduring'said bending operation, J

When the hanger is secured to the beam, 'the flanges O, 0 lie against.the side of the beam, and thearms 0' 0 lie on top thereof; and-when thehanger is fastenedin this position by screws or nails passing throughsaid sides and arms, iris believedthat the hanger has greater supportingstrength than any hanger-ever made ofeqnal weight. By supportingithehanger in part by the side flanges,'there is less danger than therewould otherwise be thatthe arms 0' C will straighten" outT whollyfoi-tinpart and thus permit-the*hangertoybe pulled loose from the beam. Anotheradt'antage of the connection 1 of the hanger to the beam by means of theside flanges, is that thereby all side motion of the hangers isdescribed hangers," a joist'may be securedto a beam as firmly asjifniortised thereto, The described hanger'may be made by'cutjting blanksalternately from opposite sides 'of prevented; and through; the

sides,'-forminj"g the arms 0' .C'; and that part the blank and attachedfrom -which the-shelf is as indicated in Figs.11

to that part thereofformed'; is cut-away,

at right angles to the body, thereby forming the flanges GO and arms 0O;

and intermediate shelf; and' the arms are bent back 'on lines 3'-4, thuscompletingthe' hangers. The-bar'shjdwn in Fig. 2 is'rolled with the twoedge flanges at-right; angles to ,the body or web. Thblanks are cut'outin the manner heretofore described; and the part 0 of the flange is cuton from that part of the blank which forms the shelf. When this form'ofbar is used, the operation of turning the flangesat right angles to thebody of the thebody, is bent on dotted lines 1 '2 toform the sides:

, G of the'saidnedge which is at the middle of p e and 2. When the blankhas been cutout, the rear side is bent blank is of course dispensedwith, or rather,

. said bending is done before the blanks are wrought metal bar, sectionseach of Which'hasi. oppositely inclined ends and unequal paralcut out.

It is advantageous to employ a bar having its sides a little thickerthan the web, because thereby the hanger will be stronger.

Having described my invention, I claim:- 1. The herein described processof making blanks for joist hangers, which consists in cutting sectionsalternately from opposite sides of a wrought metal bar, cutting theedges of said bar away from the opposite sides of adjacent sections, andleaving the edges so cutaway from each section attached to andproject-ing from the ends of the adjacent sections, substantially as andfor the purpose specified.

2. The herein described process of making blanks for joist hangers,which consists in cutting, alternately, from opposite sidesof a lelsides and arms projecting from both ends of its longer side,substantially as and for the purpose specified.

3. The herein described process of forming a wrought metal joist hanger,which consists in cutting alternately from opposite sides-oi a bar,blanks having oppositely inclined ends and unequal parallel sides, andarms which project from both ends of the long side, turning the edge ofthe long side up at right angles to the body, cutting away the middlepart 0 of said turned up edge, bending the blank to form two parallelsides and an intermediate shelf, and bending back the projecting arms,substantially as and for the purpose specified. l

In testimony whereof I atfix my signature in presence of two witnesses.
